The Galaxy S6 and Galaxy S6 Edge come with beautiful designs but those designs lack a few features that people have grown to love. One of those missing features is the microSD card slot that used to be a hallmark of Samsung's designs.
The Galaxy Note 4 is from 2014 which means that it has a microSD card slot. This means that you can expand the device's storage well beyond the stock 32GB of internal space. It also helps that microSD cards are pretty affordable.
We're not sure if the Galaxy Note 5 will have a microSD card slot or not but if Samsung opts for the premium design language, there's a chance that it will lack expandable storage. Something to keep in mind as we push into the summer.
